What are the requirements for studying and studying in Australia?

All schools look at your undergraduate grades. Basically don't think much about others. As long as your English is up to standard and your grades are enough, you can basically be admitted. Work experience will help a little, but it mainly depends on your grades.

You said that the average grade of sophomore is only about 70, so I guess your freshman grade may be even worse, only 65. So, if your average score in junior year is 80 and 85, the total average score is about 75. The Eighth National Congress is basically hopeless, and four-star universities should be able to. Australia's four-star university is not bad.

In Australian universities, we also look at the average score and the results of various subjects.

There are many other major choices. You have to go to official website to see for yourself. Different schools have different policies. The total score of IELTS is above 6.5, and the scores of all subjects are above 6.
